Explanation: $ 112 ÷ 8 h = X ÷ 40 h or $ 112 8 h = X 40 h Cross-multiply: X × 8 h = $ 112 × 40 h Divide by 8 h : X = $ 112 × ( 5 × 8 ) h 8 h = $ 112 × 5 = $ 560 Note : Of course you could have seen that 40 = 5 × 8 so the money would also be 5 × as much. Or you could have set up the ratio differently: 40 h 8 h = X $ 112 → 5 = X $ 112 → X = 5 × $ 112
